亚马逊的Alexa具有丰富的特性和功能，使其成为市场上最好的智能助手之一。它最强大的功能之一是能够将其用作对讲机。
有几种方法可以使用此功能。您可以通过单个Echo设备发布公告或同时从所有设备广播，将Alexa用作对讲机。此功能已内置，因此您无需设置 Alexa Skill(set up an Alexa Skill)或激活任何内容。以下是如何使用它。

Alexa有一个与打电话不同的独特功能。它被称为Drop In。使用Drop In，您无需等待对方回答：您只需连接到Echo即可。您可以通过其扬声器讲话并听到设备附近的任何活动。
鉴于此类功能存在潜在的安全风险(potential security risks)，您必须先启用它，然后才能使用该功能。
打开您的 Alexa 应用程序，然后点击右下角的设备。(Devices)点击回声和 Alexa(Echo & Alexa)。这将显示所有Echo设备的列表。您必须在每台设备上单独启用 Drop In(enable Drop In on each device individually)。
这可以防止该功能在您不希望有人进入的Echo上运行，例如在卧室中。(Echos)没有人愿意被一个陌生的声音吵醒。
点击设备并向下滚动到通讯。(Communications. )点按插入(Drop In)。您可以选择三种设置：开、我的家庭(On, My Household, )和关。 (Off. )
选择On仅允许允许的联系人插入(Drop)。如果您选择我的家庭，(My Household,)则只有您帐户中的设备可以插入（非常适合无需拨打电话即可联系到房子另一边的人。）如果您不希望任何人插入，请选择关闭。 (Off. )
如何进入
您可以通过两种方式加入Echo设备。
1.您可以插入特定设备。(1. You can drop in on a specific device.)第一种也是最常见的方法就是说，“Alexa，加入Kitchen Echo。” 如果您知道名称，您可以选择要连接的设备。
2. 您还可以加入特定的设备组。(2. You can also drop in on a specific group of devices.)例如，如果客厅里有多个Echo设备，你可以说，“Alexa，到客厅去。” 请记住，插入一组Echo设备有时会导致大量音频反馈，因此您可能只想插入特定设备。
如果您想与整个家庭交谈，您实际上可以要求Alexa “随处(Drop)可见” 。” 您家中任何启用了Drop(Drop) In 且未设置为“请勿打扰”的Echo(” Any Echo)设备都将连接。把(Think)它想象成与整个家庭的电话会议。
当你想结束连接时，只需说“ Alexa，end drop in”。
您也可以通过手机加入。打开Alexa应用程序，然后点击底部的通信选项卡。(Communicate)屏幕顶部有四个选项：Call、Share、Drop In和Announce。
点击插入。(Drop In. )将出现兼容设备列表。点击一个(Tap one)，您将连接。
如果您连接到带有摄像头的设备，例如Echo Show，您的接入将像视频通话一样。否则它只会是音频，但如果您只想听，可以关闭麦克风。这是父母在另一个房间时留意孩子的有用方法。
如果您想结束通话，只需点击屏幕中间的电话图标即可。
在您进入之前警告某人
Drop Ins是一项强大的功能，但最好只为家庭联系人保留。有人可能会在您不知情的情况下倾听您的声音，这存在合法的隐私问题，因为没有任何警告。
如果您想在联系之前给某人一个提示，您可以要求Alexa呼叫特定设备或点击Alexa应用程序上的呼叫(Call)图标。这将使设备在您连接之前响铃。
如何发布公告
如果您家中的每个房间都配备了Echo设备，并且您需要将每个人聚在一起吃晚饭，那么您就不想费心制作单独的公告了。相反，仅出于此目的将Alexa用作对讲机。
你所要做的就是说，“Alexa，宣布。” 然后，Alexa(” Alexa)会询问您希望您的消息说什么。您可以录制一条消息，说出您想要的任何内容，从“肉饼准备好”到“谁让狗出去了？汪(Woof)，汪，汪。”
完成录制后，网络上的每台设备都会发出提示音并广播您的消息。这是同时接触所有人的好方法。然而，公告只是单向消息。与Drop In 功能不同，通知接收者不能回话。
您也可以通过手机发布公告。导航(Navigate)到“通信(Communicate )”选项卡，然后点击“通知”。(Announce. )您可以在麦克风中输入您的信息或说些什么，它将在您的所有Alexa设备上播放。
即时连接(Instantly Connect)的免提选项(Hands Free Option)
带有公告的Alexa Drop(Alexa Drop) In 可以让您免于上下楼梯的几次跋涉。将它们与Alexa 技能和例程(Alexa skills and routines)配对，您甚至可以用它管理许多家务。您是否设置了Alexa Drop In？
How to Use Alexa as an Intercom
Amazon’ѕ Alexa is packed to the brim with features and functiоnality that make it one of the best smart assistants on the market. One of its most powerfυl features іs the ability to use it as an intercom.
There are several ways to use this feature. You can use Alexa as an intercom by making announcements from individual Echo devices, or broadcasting from all of them at once. This feature is already built-in, so you don’t have to set up an Alexa Skill or activate anything. Here’s how to use it.
Use Alexa as an Intercom With Drop In
Alexa has a unique feature that isn’t quite like calling. It’s called Drop In. With Drop In, you don’t have to wait for the person to answer: you just connect to the Echo. You can speak through its speakers and hear any activity near the device.
Given the potential security risks with a feature like this, you must first enable it before you can use the feature.
Open your Alexa app and tap Devices in the lower-right corner. Tap Echo & Alexa. This will display a list of all of your Echo devices. You have to enable Drop In on each device individually.
This prevents the feature from operating on Echos that you do not want someone to drop in on, like in the bedroom. No one wants to be woken up by a strange voice.
Tap the device and scroll down to Communications. Tap Drop In. You can choose three settings: On, My Household, and Off.
Choosing On allows only permitted contacts to Drop In. If you choose My Household, only devices on your account can drop in (perfect for reaching someone on the other side of the house without making a call.) If you don’t want anyone to drop in, choose Off.
How to Drop In
You can drop in on an Echo device in two ways.
1. You can drop in on a specific device. The first and most common method is just to say, “Alexa, drop in on Kitchen Echo.” You can choose which device to connect to if you know the name.
2. You can also drop in on a specific group of devices. For example, if there are multiple Echo devices in the living room, you can say, “Alexa, drop in on Living Room.” Keep in mind that dropping in on a group of Echo devices can sometimes result in a lot of audio feedback, so you may only want to drop in on a specific device.
If you want to speak to the entire household, you can actually ask Alexa to “Drop in everywhere.” Any Echo device in your household that has Drop In enabled and is not set to “Do not disturb” will connect. Think of it like a conference call with the entire home.
When you want to end the connection, just say “Alexa, end drop in.”
You can also Drop In through your phone. Open the Alexa app and tap the Communicate tab at the bottom. At the top of the screen are four options: Call, Share, Drop In, and Announce.
Tap Drop In. A list of compatible devices will appear. Tap one and you will connect.
If you connect to a device with a camera, like the Echo Show, your drop in will act like a video call. Otherwise it will be audio only, but you can turn off your microphone if you only want to listen. This is a useful way for parents to keep an ear on their kids while being in another room.
If you want to end the call, just tap the phone icon in the middle of your screen.
Warn Someone Before You Drop In
Drop Ins are a powerful feature, but best reserved for household contacts only. There are legitimate privacy concerns about someone potentially listening to you without your knowledge, as there is no warning for a drop in.
If you want to give someone a heads-up before you reach out, you can ask Alexa to call a specific device or tap the Call icon on your Alexa app. This will make the device ring before you connect.
How to Make an Announcement
If every room in your home is equipped with an Echo device and you need to bring everyone together for dinner, you don’t want to go through the trouble of making individual announcements. Instead, use Alexa as an intercom just for this purpose.
All you have to do is say, “Alexa, announce.” Alexa will then ask what you would like your message to say. You can record a message saying anything you want, ranging from “the meatloaf is ready” to “who let the dogs out? Woof, woof, woof.”
After you’ve finished recording, every device on your network will chime and broadcast your message. It’s a great way to reach everyone at the same time. Announcements are just one-way messages, however. Unlike the Drop In feature, announcement recipients cannot speak back.
You can also make an announcement through your phone. Navigate to the Communicate tab and then tap Announce. You can type your message or say something into the microphone and it will be played over all your Alexa devices.
A Hands Free Option to Instantly Connect
Alexa Drop In with announcements can spare you from a few trudges up and down the stairs. Pair them with Alexa skills and routines and you can even manage many family chores with it. Have you set up Alexa Drop In?
